Episode - The One with the East Germen Laundry Detergent
Continuity: Right at the start in the coffee shop Chandlers legs are always switching position depending on the angle.
Continuity: When Rachel says 'everything looks like jammies now' she is holding up a t shirt. In the next shot as she throws it down, it is now folded up.
Continuity: When Joey and Angela talk in Central Perk, the black waitress with long hair is visible the background of shots of Angela. When we see shots of Joey the same waitress is also behind him near Gunther. She is in two places at once.
Continuity: At the start of the episode when Ross says, "Multiple orgasms", you can see Chandler boot is not resting on his knee. In the next shot it has appeared from nowhere.
I'll post some more next week
